if the index is repeated. So if there are ii's in the index, it means by default you're summing from i equals 1, 2, 3, okay? The purpose of that convention

summation convention so because k summation convention so because k appears twice we're summing over k um appears twice we're summing over k um
Product of Levi-Civita symbols with contracted indices
to the Det(P_ijk P_lmn^T) = det(P_ijk)det(P_lmn^T) =det(P_ijk)det(P_lmn) = eps_ijk eps_lmn. So that’s the proof of this remarkable relationship! Some useful formulas can be derived by summing over indices. For example, the sum over i of eps_ijk eps_imn

of doing that is that means we're gonna of doing that is that means we're gonna end up summing over J and K so we got JK end up summing over J and K so we got JK
